To all whom zt may concern:

Be it known that I, SAMUEL WILSON, a citizen of the United States, residing at Chicago, in the county of Cook, and State of Illinois,.have invented certain new and useful Improvements in Overhead-*Trolley following isa specifcation. l l

This-invention relates to improvements in 4overhead trolley systems vor yelectric railways so constructed that the trolley-wheel will not leave the supply wire at line intersections or other points.

With the foregoing and other v.objects in view the invention consists in vthe combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawings which form a part of said specification and in which- Figure 1 is a side view of a portionof the supply wire showing its arch at a crossing and the particular type of trolley used. Fig. 2 is a similar view with the trolley in an altered position. Fig. 3 is a rear view of the trolley and is taken on line 3-3 of Fig. 1. Fig. 4 is an inverted plan view on line 4 4 of Fig. 1. Fig. 5 is a sectional view of a crossing where a plurality of supply wires e meet and cross. Fig. 6 is a section taken `on line 6-6of Fig.2. Fig. 7 is a longitudinal' sectional view-through a portion of the feed wire adjacent the crossing. Fig. 8 is a similar view showing a modied arch.

Like reference characters indicate corresponding arts throughout the several views.

The re erence numeral 1- designates the supply wire which at all intersections or Wire crossings is arched as at 2. I prefer to have the arches at all crossings `formed of pieces of wire mortised at each end as at 3 to recelve tenons 4 of the main supply wire; said tenons being of smaller diameter than the wire 1. The arched piece 2 is pro-.

vided with a set screw 5 adapted to engage the tenon 4 and retain it in an adjusted position in the said arched piece. This `construction permits the formation of a narrow or wide arch as desired or of thechange of one form ofA arch to the other readily. Circular collars 6, also made of wire, maybe placed about the portion of the tenon 4 between the main wlre and the end of the arch to properly ll outsaid tongue.

Specication of Letters Patent.

My trolley'comprises the pole 7 pivotally f ratentedJu1y4-,19i16. application' mea nay e, 191s. serial Np. 28,200. f l' carried in bearings-8 arranged upon the base 9 which 'is pivotally carried upon the roof of the ear 10;' said pole being provided'with the cross piece fllto which the anchor cord 11" is secured-andito which springs 12, 212

are-also securedi''jthat :connect withthe tension vpoles"13,""i1 j.alsoL pivotally carried upon `thesaid base 9. l'The upper end-of the pole 7 is bifurcatedv to receive the shaft 14 that carries the trol-leyA wheel 15 and thatals'o carries the'arched frame 16, 16 in Whi'chlthe ide spools '17,18'y are terminally carried.` he trolley `wheel 15 is formed 'with' -a grooved periphery to engage vwith the supply wire and the spools17, 18 arranged in the front and' vrear of the wheel 15 permit` fthe` device to pass vvover a crossing, such as is illustrated inlFigs and 6, without danger of jumping 'the' wire. In Fig. 2 the trolley wheel is shown'. just about to pass the crossing 'andfin-Fig. 1 the trolley wheel has -Ajustj left'the supply` wire. andthe spool 18 'hasengaged'it and will ride alon' it until thev wheel 15 v"picks it up again.'` he' tension oles 13 and springs 12 cause-the spools 1 f, 18 to pick up the supplywire as soon as the trolley 'wheel leaves it.

What is claimed-is:-

The combination vwith an electrically propelledvehicle, of an elevated supply wirel formedl with@ extensible arched portions soi at its l,intersecti'on: with other supply wires,

trolley pole carried b said base, tension poles carried by said ase and .operatively connected to said trolley pole, a trolley wheel carried by .said trolley pole, a frame fast upon the axle of said trolley wheel, and

spools carried -by said frame and positioned in advance and in the rear of said trolley In testimony that I claim the foregoing as my own Ijhave heretoalxed my signa-ture in the presence of two subscribing witnesses.
